ROOFING AND SIDING STRIP.

SPECIFICATION forming part of iLetters Patent No. 498,1 11, dated May23, 1893.

I Application filed May I1, 1892- Serial No. 432,689- (No model.)

T0 at whom it may concern.-

Be it known that 1, JAMES W. HAMMETT, of Eureka, in the county ofPleasant and State of West Virginia, have invented a new and usefulImprovement in Roofing and Siding Strips,of which the following is aspecification.

My invention is an improvement in roofing and siding strips and consistsin the novel construction and combination of parts hereinafter describedand pointed outin the claims.

In the drawings, Figure 1 is a perspective view of a part of a houseprovided with my improvements. Fig. 2 is a cross sectional view throughone of the strips. Fig. 3 shows the strip sections in detail, and Fig. 4is a diagrammatic end view illustrating the rounding and hollowing ofthe contact surfaces of the sections, the curvature being somewhatexaggerated to aid the illustration.

The strips are shown as applied to a house but manifestly they can beused on cars or elsewhere as may be desired without departing from someof the broad principles of my invention. The strips are formed of innerand outer sections A and B, pressed at their adjacent faces against thesheets 0 of tin or other material and having such faces corrugated asshown. The corrugations of the two sections are arranged in line so thatthe ridge or crown of the corrugations is immediately opposite and whenthe two sections are drawn together do not tend to bend the plates orboards down into the hollows of corrugations. These hollows it will beseen form dead air spaces or packings and prevent the wind from carryingrain, snow or cold air through the roof or siding. This doublecorrugated construction also permits the drying out of any dampness thatmay come between thestrips and which would otherwise result in decay. Bypreference the inner section hasits corrugated face made slightlyrounded, and that of the outer section slightly hollow, the hollows ofthis outer section being slightly greater than the curvature or swell ofthe inner section allowing the corrugation nearer the edges of thesections to come in contact with the roofing or siding plates before thecenter ones' do, so that as the clamps, shown as screws D, which aredriven through the inner section into the outer one, are drawn downtight they will spring the middles of the sections sufficiently to bringall the corrugations closely against the roofing or siding sheets. Therods or nails E which are of tempered spring steel and pass transverselythrough or nearly through the strips are thus brought into action andkeep the joints so formed tight.

In forming the corrugations in the sections it is preferred to form oneor both with a flat central portion at a so as to avoid any possibilityof the sections being drawn so tightly as to be slipped slightly to onesideand force the roof or side sheet-s into the hollows of thecorrugations. Manifestly the roofing or siding sheets may be of anydesired material.

Having thus described my invention, what I claim is 1. An improvedroofing and siding strip composed of inner and outer sections and aclamp for drawing such sections together, the adjacent faces of saidsections being formed with corrugations and the ridges or crowns of thecorrugations of one section being arranged opposite those of the othersubstantially as and for the purposes set forth.

2. The roofing and siding strip herein described consisting of the innerand outer sections having their adjacent faces formed one rounded andthe other hollowed and both corrugated substantially as and for thepurposes set forth.

3. The roofing and siding strip herein described consisting of the innerand outer sections having their adjacent faces corrugated and providedwith the transverse rails or rods E substantially as and for thepurposes set forth.

4. The combination of the sheets 0 the strips formed of inner andoutersections having their adjacent faces provided with corrugations thehighest parts of the corrugations of one strip being arranged oppositethose of forth.
